Final answer:
Water pollution is a problem caused by industries that leads to contaminants entering water bodies and harming the environment and human health. It can result in dead zones with low oxygen levels and contamination of the food chain. Preventative measures include reducing runoff and properly disposing of industrial waste.
Step-by-step explanation:
Water pollution is a significant issue caused by industries. It occurs when contaminants enter water bodies, such as rivers or lakes, and harm the environment and human health. Industrial waste, pesticides, stormwater runoff, and acid rain are some examples of pollutants that contribute to water pollution.
One consequence of water pollution is the creation of dead zones, which are areas with low oxygen levels due to excessive algae growth. These dead zones can be detrimental to aquatic life. Additionally, water pollution can contaminate the food chain, leading to the consumption of harmful substances by humans.
Preventing water pollution requires reducing runoff through measures like limiting fertilizer use and preserving wetlands. Proper disposal and treatment of industrial waste are also essential in addressing this issue.
